"Sports anime veterans would understand how important this episode of Ace of Diamond was for the series. As with many sports series, Ace of Diamond began with some stage setting. Both this episode and the first episode are really all about putting all the pieces into place before the series truly kicks in. Now this can be a strange experience for those uninitiated in the sports genre as it often means that many characters introduced early on become inessential later on, contrary to a standard anime which generally introduces the important players from the get go.
What makes this episode important for Ace of Diamond is that it completes the preamble before the big game. The stage is set and Ace of Diamond is ready to play ball. That’s not to say that these first two episodes have been without incident, because that would be far from the truth, in fact a hell of a lot has happened in the span of these two episodes and in particular this episode really turned things up to 11."
